FREEWELL 67mm M2 Magnetic Quick Swap Base Ring camera accessory

SKU CH-CSJR-H5PSF

A 67 mm magnetic base ring that lets you swap M1 and M2 filters instantly without threading

  • Magnetic quick-swap system speeds filter changes
  • Works with M1 and M2 magnetic filters
  • 67 mm thread fits compatible lenses directly
  • Scratch-resistant build protects the front element
  • High light transmission reduces vignetting in shots

67 mm Magnetic Quick Swap Base Ring

The Freewell 67 mm M2 Magnetic Quick Swap Base Ring threads onto a lens filter thread to provide a magnetic mounting point. It is built for photographers who want to swap M1 or M2 magnetic filters rapidly without threading each one. The ring is not a converter for standard threaded filters and will not work with non-magnetic filter systems.

67 mm filter thread compatibility

This specific base ring fits lenses with a 67 mm front filter thread. The same M2 system is also offered in 77 mm and 82 mm sizes for other lens diameters. Selecting the correct thread size is the only specification that determines whether the ring will mount securely on a given lens.

Scratch resistant construction for daily use

High grade materials give the empty base ring strong scratch resistance to protect the lens front element during frequent filter changes. The design maximises light transmission to reduce vignetting and preserve image clarity in normal shooting conditions. No power, cooling or noise considerations apply to this passive accessory.

Questions about this item

Does the 67 mm thread size fit my lens directly?

Yes, the 67 mm thread screws straight onto any lens with a matching 67 mm filter thread; 77 mm and 82 mm versions are also available for other lens diameters.

Will the magnetic mount hold M1 and M2 filters securely in active use?

The ring is engineered specifically for the M1 and M2 magnetic quick-swap systems, so compatible filters lock on magnetically and release with a deliberate twist.

How much clearance does the base ring add in front of the lens?

The ring sits flush on the filter thread and adds only the thin profile needed for the magnetic interface, keeping vignetting to a minimum on wide-angle lenses.
